Which factors put species at risk?
|
habitat reduction
habitat fragmentation small population size genetic erosion in a population the commercial value of a species |
|
What are the consequences of habitat fragmentation?
|
Habitat fragmentation can prevent inter-breeding between the isolated sub-populations of species.
This results in inbreeding, genetic erosion, and reduced overall health. |
|
What are wildlife corridors?
|
Wildlife corridors connect habitat fragments. They allow interbreeding between isolated sub-population.
|
|
What is a major benefit of a corridor that connects reserves in biodiversity hotspots?
|
Corridors that connect reserves in biodiversity hotspots can have a magnifying effect that increases species number.
|
|
What is population augmentation?
|
Population augmentation is the introduction of genetically-distinct individuals into a genetically-eroded sub-population to create genetic variation.
|
|
What are major risk factors for marine ecosystems?
|
The loss of key biodiversity centers is a major risk for marine ecosystems.
fishing |
|
What are the causes of coral reef ecosystem decline?
|
disease, changes in temperature, and changes in pH
|
|
What is the use of plants in bioremediation called?
|
phytoremediation
|
|
What is bioremediation?
|
Bioremediation is the use of select species to reduce toxin levels in contaminated water and soils.
|
|
What is restoration ecology?
|
Resoration ecology seeks to initiate or accelerate the recovery of degraded ecosystems.
